Power pistol loads were extremely accurate especially the 5.2gr load (see picture below). Cfe pistol accuracy was not as good as Power pistol but still acceptable. I shot at 20 yds from the bench. Lower charge weights of both powders cycled the gun but just barely, cases were slighy sooty, as charge weight increased ejection got better and cases got less and less sooty (obviously right?) The 5.2 grain loads of both powders seemed perfect. I'll be making up 100 of each 5.2gr load tonight for testing tomorrow in the p210.
Do these numbers jive with anyone else's testing? Especially Power pistol?
